[0038] The transparent end cover 8 is sleeved on the straight section 7 and can slide along the straight section 7 to cover the feeding opening 9.

[0039] The drum 4 is provided with a peeling structure for smoothing the surface of the longan.

[0040] In the process of making longan into longan dry, the peeling process is a relatively important link. At present, manual peeling is time-consuming and laborious, so the utility model drives the peeling structure by the driving motor 26 to peel, so as to remove small bumps and bump particles on the surface of the longan shell, so that the shell is smoother, the permeability is increased, and the finished product is easy to dry and beautiful.

[0041] Specifically, the peeling structure comprises a poking piece 19 and a protruding block 25, and the poking pieces 19 are uniformly and spacedly distributed at the bottom of the drum 4. Figure 3 And Figure 4 As shown in the drawings, the poking piece 19 is installed at the bottom in the cavity of the drum 4, and when the driving motor 26 drives the drum 4 to rotate, the friction of the abrasive is increased, so that the longan shell is better thinned and peeled.

[0042] Meanwhile, the convex block 25 is beneficial to tumbling of the longans in the roller 4 during rotation of the roller 4, so that the longan surface is uniformly sanded, and the sanding effect is good.

The end cover 8 is provided with a handle 13 symmetrically relative to the straight section 7. The end of the straight section 7 is provided with a filter end cover 20 with a filter hole. The filter end cover 20 is used to limit the end cover 8 from falling off the straight section 7.

[0045] The utility model discloses, Figure 1 When the end cover 8 is far away from the feeding opening 9 before feeding, the worker holds the two handles 13 and then lifts up. The symmetric sliding parts 10 can slide upwards in the vertical slots 11 respectively. When the sliding parts 10 slide to the top ends of the vertical slots 11, the end cover 8 is rotated by rotating the handles 13. The sliding part 10 enters the horizontal slot 12. In this way, the end cover 8 is limited to be a certain distance away from the feeding opening 9. At this time, the feeding opening 9 is opened, and the longans can be added into the roller 4 from the feeding opening 9.

[0046] When the longans to be sanded are added into the roller 4, the handles 13 and the end cover 8 are reversely rotated, so that the sliding part 10 reenters the vertical slot 11 from the horizontal slot 12. The end cover 8 slides downwards until the feeding opening 9 is covered.
